The following is not for the faint of heart!! Consider yourself warned.

I think you may be right about the blunt tip moving things out of the way. One thing I did not mention earlier in fear of grossing people out, was that the surgeon made a fairly bizarre discovery while clean my wound.

Near the end of the cleaning of my exit wound, I heard him say, “Well, look what I found!!?”

Needless to say, this instantly sparked my curiosity. With tweezers in hand, he held a perfectly square piece of my palm in front of my eyes. It was about 3/16 inches square. He then asked me if the drill bit happened to have a square end.
